----------------------------------------------------------
This problem seems to be gone after I uninstalled the new "Gradle" and "Groovy
and Gradle" plugins. I had installed the older "Gradle Support" plugin, and
thought that having the newer plugins disabled would prevent conflicts between
the two. But apparently "disabled" is not equivalent to uninstalled.
So now I'm unsure whether or not this ticket is still relevant. It may be that
this is still a bug, but my configuration change just means I'm no longer
hitting it?

> ArrayIndexOutOfBoundsException during "Find Usages" operation

> Key: NETBEANS-2354
> URL: https://issues.apache.org/jira/browse/NETBEANS-2354
> Project: NetBeans
> Issue Type: Bug
> Components: java - Refactoring
> Affects Versions: 11.0
> Reporter: Travis
> Priority: Major
>
> I'm using Netbeans 11 vc4 on Java 8 multi-project (on Windows). I ran "Find
> Usages" on a method and got the exception below. After this exception, the
> find results were empty, despite there being callers of the method within the
> search scope.
>
> I have spent a ton of time working with the same project using Netbeans 10,
> and running "Find Usages" frequently. I never got this exception there
> before, and Find Usages has been totally robust until now. So it seems this
> is likely a new bug in Netbeans 11.
>
> I cannot provide the gigantic multi-project where this problem is
> reproducible. I could try to reduce it down to a minimal testcase and then
> obfuscate the code, if you need an example project to reproduce this issue or
> to test the fix.
>
> Thanks!
